Hello John,
?
I will respectfully disagree with your comment of the drill
bits from HF (Harbor Freight).
?
Now while I did have a small drill bit set from HF?back
in the late 70's that was of very poor quality, improperly ground tips, bent
drills right out of the box,?questionable hardness -?dulled
immediately.?I know that the quality has now improved. I purchased a 115
drill bit set from HF?a while back and was very pleasantly surprised by its
quality. Now I did buy the more expensive?Cobalt drill bit?set
($109.99) fearing the quality of the lower end HSS ($34.99) or Titanium M2
coated set ($49.99). All of these prices are list every day prices, and often go
on sale and of course take off an extra 25% with a coupon.
?
I'd have no problem recommending them to anyone looking
fro a set of drill bits

If the material is not hardened, I would just use a good high-speed
steel drill.
I would not use any drill from HF since they are suspect.
